Optimized joint document review

ABSTRACT

A UI for presenting and reviewing a document is optimized based upon the type of computing device being utilized to present the document. One such UI includes a first pane showing a view of the document under review that is sized and formatted for display on a large-format display device. The first pane can also be utilized to emphasize a portion of the document. The UI also includes a second pane that includes indicators for each of the reviewers of the document. The selection of an indicator will cause a portion of the document being reviewed by the corresponding reviewer to be displayed in the first pane. The UI also includes a third pane that includes a scaled image of the document shown in the first pane. Selection of a portion of the scaled image causes the selected portion of the document to be displayed in the first pane.

RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 12/968,287, filed Dec. 15, 2010, and entitled “Optimized Joint Document Review,” which is hereby incorporated by reference.

BACKGROUND

Joint review of an electronic document often involves a single computer connected to a large-format display device, such as a projector. The program utilized to create the document, such as a word processing application program, is typically utilized to present and navigate the document under review. Document reviewers typically follow along with the display of the document on the large-format display device. In practice, this leads to all of the document reviewers viewing exactly the same content. Moreover, because the user interface provided by the document creation program is not optimized for a large-format display device, the document as presented may be difficult to read.

Some document reviewers might also opt to open a copy of the document under review on their own computing device, such as a laptop computer. The review of the document by these reviewers, however, occurs in a manner that is disconnected from the review of the document by the other reviewers. Consequently, the common joint review practices described above can lead to considerable manual navigation within the document under review, especially for long documents. Moreover, the user interface provided by the document creation program may not be configured to take advantage of enhanced capabilities provided by each reviewer's computing device.

It is with respect to these and other considerations that the disclosure made herein is presented.

SUMMARY

Technologies are described herein for enabling the joint review of documents. Through an implementation of the concepts and technologies presented herein, documents can be reviewed jointly in an efficient and effective manner. In particular, a user interface (“UI”) for presenting a document can be optimized based upon the type of computing device being utilized to present the document. For example, a UI that provides functionality for document review may be customized for use on large-format display devices and other device types. Additionally, document navigation mechanisms may be customized with support for touch-enabled display devices and gesture input, UIs for emphasizing portions of a document may be provided, and UIs may be provided for identifying the portions of the documents under review by each reviewer.

According to one aspect presented herein, a group of people, who may be referred to herein individually as “reviewers” or “document reviewers,” can jointly review an electronic document. A UI for reviewing the document can be provided that is customized based upon the type of computing device that each reviewer is utilizing. For instance, unique UIs can be provided for desktop or laptop computers, tablet computing devices, wireless mobile telephones, and large-format displays. Each UI can be customized to take advantage of the available user input mechanisms. For instance, the UIs may be optimized for touch input, gestures, and other types of input. Moreover, the location of each reviewer within a document under review may be shared between the devices, communicated to the reviewers, and utilized to assist in document navigation.

According to another aspect, a UI is provided for joint review of a document. In one implementation, the UI is configured for use on a large-format display device, such as a large touch-enabled video display. The UI includes a first UI element, such as a UI pane, showing a view of the document under review. When a large-format display device is utilized, the view may be sized and formatted for display on a large-format display device. For instance, a font style and size may be selected that are appropriate for viewing the document from a distance. Additionally, pagination and other elements traditionally associated with a paper document might not be displayed in the view of the document shown in the first UI pane. Conventional UI tools for editing a document might also be eliminated from the UI. The view of the document shown in the first UI pane may be navigated utilizing touch input, gestures, or other supported UI mechanisms.

The UI might also include a second UI element, such as a second UI pane. The second UI pane might include indicators for each of the reviewers of the document. Each indicator might include data identifying the reviewer, an image of the reviewer, data indicating the type of review being performed (e.g. reading or editing), and an indication of the type of device being utilized (e.g. a tablet or a phone). In one implementation, the selection of an indicator will cause a portion of the document being reviewed by the corresponding reviewer to be displayed in the first UI pane. In this manner, the indicators can be utilized to quickly navigate to the portion of the document under review by each of the reviewers. In alternate embodiments, one reviewer can “push” their location in a document to other reviewers, thereby allowing one reviewer to synchronize their location in a document to other reviewers. Additionally, the view shown to each reviewer might automatically follow along with the location of another reviewer.

According to another aspect, the UI also includes a third UI element, such as a third UI pane, for enabling navigation of the document shown in the first UI pane in a manner optimized for a particular display size and input type. For instance, in one embodiment the third UI pane includes a scaled image, such as a “thumbnail” image, of the document shown in the first UI pane. Selection of a portion of the scaled image causes the selected portion of the document to be displayed in the first UI pane. The UI might also be optimized for a particular display size and input type. For instance, on a large display, a visual thumbnail might be provided in the manner described above that can be utilized to quickly navigate the document with simple gestures. On a smaller display, such as a mobile telephone, the third UI pane might include a mechanism for navigating between headings in the document rather than a thumbnail. Other variations might also be utilized.

In other embodiments, the third UI pane includes a view of sections of the document. Selection of a section of the document in the third UI pane causes the selected section of the document to be displayed in the first UI pane. The third UI pane might also provide an indication of recent viewing or editing activity within the document by the reviewers. The third UI pane might also provided functionality for browsing by heading, figures, or other document elements. The view shown in the third pane might also be utilized to navigate the document independently of the view shown in the first UI pane.

According to another aspect, the first UI pane can be utilized to emphasize a portion of the document. For instance, in one embodiment a portion of the document, such as a paragraph, can be selected in the first UI pane. In response to the selection of a portion of the document, the other portions of the document shown in the first UI pane may be obfuscated. For instance, the other portions of the document may be “blurred” or “fogged” over, thereby rendering the other portions unreadable. In this manner, the attention of the reviewers may be focused on a selected portion of the document.

The UI elements disclosed herein and the user experience provided for interacting with those panes might also be customized based upon the type of device utilized by each reviewer. For example, when a sufficiently large display is available, each pane may be displayed separately or also inline with the document being reviewed. On a mobile telephone the panes may be displayed individually and UI elements may be provided for allowing a user to navigate between the panes. It should be appreciated that although UI panes have been utilized herein to describe various features, other types of UI elements such as “fly out” menus, overlays, and other types of UI elements and UI controls might also be utilized.

This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended that this Summary be used to limit the scope of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.

The large-format display controller 106 may be a computer system configured appropriately for driving the large-format display device 102.

As shown in FIG. 1 , the large-format display controller 106, smartphone 110, tablet computer 112, and desktop/laptop computer 114 are each configured to execute an editing program 116. The editing program 116 is a program configured for creating and editing the document 120. As will be described in greater detail below, the editing program 116 is also configured in embodiments herein for providing functionality for allowing the document 120 to be jointly reviewed by users of the large-format display device 102, smartphone 110, tablet computer 112, and desktop/laptop computer 114. According to implementations, the editing program 116 may be a program for creating and editing word processing documents, presentation documents, spreadsheet documents, or other types of electronic documents. It should be appreciated that different versions of the editing program 116 can be executed on each of the devices shown in FIG. 1 . The different versions may be configured to interoperate in the manner disclosed herein.

In one implementation, a meeting server 108 is utilized to coordinate the review of the document 120. In this regard, the meeting server 108 may execute a meeting service 118. Through the use of the meeting service 118, a meeting may be scheduled for reviewing the document 120. Appropriate invitations may be sent to the individuals that will be reviewing the document 120. The meeting server 108 might also provide other functionality for facilitating, scheduling, and managing a document review meeting. It should be appreciated that while the document 120 is illustrated in FIG. 1 as being stored at the meeting server 108, the document 120 may be stored in any location accessible to the editing program 116. It should also be appreciated that the embodiments disclosed herein might be implemented without the use of the meeting server 108.

It should be appreciated that each of the computing devices illustrated in FIG. 1 may provide various types of user input mechanisms and various output capabilities. For instance, the large-format display device 102 may include touch input capabilities allowing the reviewer 104 to provide input to the editing program 116 executing on the large-format display controller 106 by touching the large-format display device 102. In this regard, the editing program 116 might support the use of touch gestures to indicate various types of input.

The smartphone 110 might also support touch input, but typically includes a small-scale display screen. In other embodiments, the smartphone 110 might not provide touch input. The tablet computer 112 might provide touch input on a medium-sized display screen and the desktop/laptop computer 114 may or may not be equipped with touch input and may provide a medium-sized display.

As will be described in greater detail below, the editing program 116 provides a UI for presenting and collaboratively reviewing the document 120 that is optimized based upon the type of computing device utilized to present the document. For instance, in one implementation, a UI is provided for document review that is customized for use on the large-format display device 102. In alternative embodiments, the UI might be customized for use on the smartphone 110, the tablet computer 112, and the desktop/laptop computer 114.

As will also be described in greater detail below, the editing program 116 executing on each of the devices in FIG. 1 may be configured to provide an indication of the location within the document 120 currently under review by a user of the respective device. UIs may be provided herein that identify the portions of the document 120 under review by each reviewer and that permit easy navigation to the portions of the document currently under review. Moreover, UIs are provided that permit one reviewer to “push” their location in a document to other reviewers, thereby allowing one reviewer to synchronize their location in a document to other reviewers. Additionally, the view shown to each reviewer might automatically follow along with the location of another reviewer. Additionally, UIs will be described herein for emphasizing portions of the document 120 when used in a group review session setting, such as through the use of the large-format display device 102. Additional details regarding these UIs will be provided below with reference to FIGS. 2-5 .

It should be appreciated that although FIG. 1 illustrates four computing devices executing the editing program 116, many other such devices might be utilized by the concepts and technologies presented herein. Additionally, it should be appreciated that while a single network 118 is illustrated in FIG. 1 that connects the computing devices, many other such networks might be utilized. Moreover, although a meeting server 108 and meeting service 118 have been illustrated in FIG. 1 , it should be appreciated that the embodiments described herein are not dependent upon the use of a meeting server 108 or a meeting service 118 to organize and facilitate a review meeting.

FIG. 2 is a UI diagram showing one illustrative UI disclosed herein for optimized document presentation and navigation on a large-format display device 102, according to one embodiment disclosed herein. In particular, FIG. 2 shows a UI 200 suitable for joint review of a document on the large-format display device 102. In the particular embodiment shown in FIG. 2 , the UI 200 includes three UI panes 202A-202C. The UI pane 202A includes a view of the document 120 that is sized and formatted for display on the large-format display device 102. For instance, a font style and size may be selected that are appropriate for viewing the document 120 from a distance. Additionally, the view of the document 120 shown in the pane 202A is simplified to remove pagination and other elements traditionally associated with a paper document. In this regard, the UI 200 also does not include conventional UI tools for editing a document. In this manner, the UI 200 is focused on review of the document 120 rather than editing of the document 120.

The pane 202A may be utilized to navigate the contents of the document 120. For instance, a touch enabled large-format display device 102 may be utilized to make input into the pane 202A for scrolling the visible portion of the document 120 up or down. As an example, a “swipe” touch gesture might be utilized to scroll the view of the document 120 shown in the pane 202A. Other types of gestures might also be made into the pane 202A to scroll the view of the document 120 visible within the pane 202A.

According to one implementation, no editing of the document 120 is permitted within the pane 202A. According to another embodiment, simple editing functionality may be provided within the pane 202A, such as functionality for generating an ink drawing, highlighting a portion of the document 120, or inserting comments into the document 120. In general, it should be appreciated, however, that the pane 202A is configured in a manner so as to avoid inadvertent modification of the document 120.

As shown in FIG. 2 and described briefly above, the UI 200 also includes a UI pane 202B. The UI 202B includes indicators 204A-204C for each of the reviewers of the document 120. Each of the indicators 204A-204C includes an image 206A-206C of the corresponding reviewer, text indicating the type of review being performed (e.g. reading or editing), and an indication of the type of device being utilized (e.g. a tablet or a phone). For instance, the indicator 204A indicates that a reviewer named “Joe” is reading the document 120 from his smartphone 110. The indicator 204B indicates that a reviewer named “Jeff” is editing the section of the document 120 shown in the pane 202A from his computer 114. The indicator 204C indicates that a reviewer named “Nathan” is reading the document 120 on a tablet computer 112. It should be appreciated that while three indicators 204A-204C are illustrated in FIG. 2 , more or fewer indicators may be shown in the pane 202B depending on the number of individuals currently reviewing the document 120. Additionally, it should be appreciated that an appropriate user input mechanism might be utilized to scroll the contents of the pane 202B when the number of indicators 204A-204C exceed the available space within the pane 202B.

According to one implementation disclosed herein, the indicators 204A-204C may be selected in order to navigate the view of the document 120 shown in the pane 202A to the portion of the document currently being reviewed by the corresponding reviewer. For instance, the indicator 204A may be selected. In response there to, the portion of the document 120 shown in the pane 202A may be modified to show the portion of the document 120 currently being read by the user named “Joe”. Likewise, the indicator 204C might be selected in order to cause the view of the document 120 shown in the pane 202A to reflect the portion of the document 120 being read by the user named “Nathan” on his tablet 112. In this manner, the indicators 204A-204C can be utilized to quickly navigate to the portion of the document 120 under review by each of the reviewers.

It should be appreciated that, in alternate embodiments, one reviewer can “push” their location in a document to other reviewers, thereby allowing one reviewer to synchronize their location in a document to other reviewers. For instance, a reviewer utilizing a mobile telephone to review a document could “push” their location in the document to other reviewers using desktop computers or other types of devices. Additionally, the view shown to each reviewer might automatically follow along with the location of another reviewer.

As also shown in FIG. 2 and described briefly above, the user interface 200 also includes a UI pane 202C. The UI pane 202C includes a scaled image 208, such a “thumbnail” image, of the document 120 currently under review. The UI pane 202C might also include a bounding box 210 that indicates the portion of the document 120 currently being shown in the pane 202A. The user may select a portion of the scaled image 208 shown in the pane 202C. In response thereto, the portion of the document 120 corresponding to the selection made in the pane 202C will be displayed in the pane 202A. In this manner, virtually any portion of the document 120 can be quickly navigated to.

In one implementation, the pane 202C also includes a traditional scroll bar 212 in the event that the scaled image 208 exceeds the available space in the pane 202C. The scroll bar 212 may be utilized to scroll the view of the scaled image 208. The pane 202C might also include a UI control 214 for modifying the font size of the view of the document 120 shown in the pane 202A, a UI control 216 for hiding the pane 202B, a UI control for editing the document 120 in the editing program 116, and a UI control 220 for setting other options regarding the operation of the UI 220.

According to other embodiments, the pane 202C might include a visualization of sections or elements within the document 120. For instance, the pane 202C might include a visualization of the pages, headers, embedded content, comments, sections, or other elements within the document 120. By selecting any of the visualizations within the pane 202C, a user may quickly modify the view of the document 120 shown in the pane 202A to reflect the selected portion of the document. In this manner, the pane 202C may be utilized to quickly navigate to virtually any portion of the document 120. The pane 202C might also provide an indication of the portion of the document 120 currently being reviewed by each reviewer.

It should be appreciated that the UI elements disclosed herein and the user experience provided for interacting with those panes might also be customized based upon the type of device utilized by each reviewer. For example, when a sufficiently large display is available, each pane may be displayed separately or also inline with the document being reviewed. On a mobile telephone the panes may be displayed individually and UI elements may be provided for allowing a user to navigate between the panes.

FIG. 3 is a UI diagram showing one illustrative UI disclosed herein for optimized document presentation and navigation on a desktop or laptop computer, according to one embodiment disclosed herein. In particular, FIG. 3 shows a UI 300 that may be displayed by a desktop/laptop computer 114 or another computing device having an average-sized display screen. In the UI shown in FIG. 3 , a UI pane 302A includes indicators 304A-304C identifying the reviewers currently reviewing the document 120.

The indicators 304A-304C may include images or text identifying the user, the type of review in progress, the type of device upon which the review is being performed, and other information. The pane 302A might also include UI controls for performing other review and related tasks, such as a UI control 306 for screen sharing, a UI control 308 for requesting that other users open the document 120, a UI control 310 for opening a meeting, and a UI control 312 for opening other meeting files.

The UI 300 shown in FIG. 3 also includes a UI pane 302B. The UI pane 302B provides a view of the document 120. The view of the document 120 shown in the pane 302B may be navigated in a traditional fashion utilizing the scroll bar 316 or other user input mechanisms.

In the example shown in FIG. 3 , the view of the document 120 shown in the pane 302B also includes the indicators 314A-314C. The indicators 314A-314C identify the reviewers currently reviewing the document shown in the pane 302B. Additionally, the indicators 314A-314C provide an indication as to the portions of the document 120 currently under review. For instance, in the example shown in FIG. 3 , the indicator 314B includes an arrow pointing at the overview section of the document 120. This indicates that the user named “Jeff” is currently reviewing this portion of the document 120. The indicators 314A and 314C include arrows pointing off screen. These indicators show that the users named “Joe” and “Nathan” are currently reviewing portions of the document 120 that are below the portion shown in pane 302B. The indicators 314A-314C may be selected in order to navigate the view of the document 120 shown in the pane 302B to the portion of the document 120 currently under view by the respective reviewer.

FIG. 4 is a UI diagram showing one illustrative UI disclosed herein for emphasizing a portion of a document, according to one embodiment disclosed herein. In particular, FIG. 4 shows a UI 400 that may be utilized within the UI 200 or the UI 300 to emphasize a portion of the document 120. In the UI 400, a portion 402A of the document 120 may be selected. For instance, selection may be made utilizing an appropriate touch-enabled input device. Once the portion 402A of the document 120 has been selected, a request may be received in order to emphasize the selected portion 402A. An appropriate UI gesture or other type of user input may be received in order to make such a request.

In response to receiving a request to emphasize the selected portion 402A, the editing program 116 is configured to obfuscate the other portions of the document 120 displayed in the UI 400. For instance, the portion 402B of the document 120 may be “blurred” or “fogged” over, thereby rendering the portion 402B of the document 120 unreadable. Additionally, the text size or other visual attributes of the portion 402A may be emphasized. For instance, the font size of text within the portion 402 may be increased. Additionally, separators 404A-404B may be displayed to further distinguish the portion 402A of the document 120 from the remaining portion 402B of the document 120. It should be appreciated that other types of visual effects might also be applied to the non-selected portion 402B of the document 120. A UI control 406 might also be displayed which, when selected, will cause the emphasis to the portion 402A to be removed from the UI 400. In this manner, the attention of the reviewers may be focused on the selected portion 402A of the document 120.

It should be appreciated that the user interfaces as illustrated in FIGS. 2-4 and described above are merely illustrative and that other implementations may be utilized. It should be further appreciated that the various UI components illustrated in FIGS. 2-4 and described above may be used in combination. For instance, the UI 400 may be utilized in the UI pane 202A shown in FIG. 2 or the UI pane 302 shown in FIG. 3 . Similarly, the indicators 314A-314C might be utilized in the UI pane 202A or the UI pane 202C.

FIG. 5 is a flow diagram showing a routine 500 that illustrates aspects of one process disclosed herein for optimized document presentation and navigation for presenting a document in a meeting. It should be appreciated that the logical operations described herein with respect to FIG. 5 and the other FIGURES are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as operations, structural devices, acts, or modules. These operations, structural devices, acts and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof. It should also be appreciated that more or fewer operations may be performed than shown in the figures and described herein. These operations may also be performed in a different order than those described herein.

The routine 500 begins at operation 502, where the editing program 116 is launched on the various devices utilized to review the document 120. For instance, as described above, the editing program 116 may be launched on the large-format display controller 106, the smartphone 110, the tablet computer 112, and the desktop/laptop computer 114. Once the editing program 116 has been launched, the routine 500 proceeds to operation 504.

At operation 504, the editing program 116 retrieves the document 120 to be jointly reviewed. The routine 500 then proceeds to operation 506 where the editing program 116 identifies the device type, display form factor, and input devices of the device upon which it is executing. Once these items have been identified, the routine 500 then proceeds to operation 508 where the editing program 116 provides a user interface customized for reviewing the document 120 that is suitable for the display and user input mechanisms provided by the identified device. For instance as described above, the UI 200 shown in FIG. 2 may be provided by the editing program 116 executing on the large-format display controller 106. Similarly, the UI shown in FIG. 3 and described above may be provided by the editing program 116 executing on the desktop/laptop computer 114. Additionally, various aspects of the UIs described herein might be provided by a suitable UI on the smartphone 110 and the tablet computer 112.

From operation 508, the routine 500 proceeds to operation 510. At operation 510, the editing program 116 executing on each device provides an indication to the other devices as to the location in the document currently being reviewed. Each of the editing programs 116 receives this information and provides an indication as to the location in the document of the other reviewers. For instance, the contents of the pane 202B described above with reference to FIG. 2 may be provided indicating the location of reviewers within the document 120. Similarly, the indicators 314A-314C may be displayed showing the location within the document 120 currently being reviewed by the other reviewers.

From operation 510, the routine 500 proceeds to operation 512 where the editing program 116 also provides other UI features for navigating the document 120 and emphasizing portions of the document 120 for review. These features may be based upon the particular device type upon which each instance of the editing program 116 is executing. These features were described above with reference to FIGS. 2-5 . From operation 512, the routine 500 proceeds to operation 514, where it ends.

FIG. 6 is a computer architecture diagram showing an illustrative computer hardware and software architecture for a computing system capable of implementing the various embodiments presented herein. The computer architecture shown in FIG. 6 illustrates a conventional desktop, laptop computer, or server computer and may be utilized to execute the various software components described herein.

A basic input/output system (“BIOS”) containing the basic routines that help to transfer information between elements within the computer 600, such as during startup, is stored in the ROM 616. The computer 600 further includes a mass storage device 610 for storing an operating system 618, application programs, and other program modules, which will be described in greater detail below.

The mass storage device 610 is connected to the CPU 602 through a mass storage controller (not shown) connected to the bus 604. The mass storage device 610 and its associated computer-readable storage media provide non-volatile storage for the computer 600. Although the description of computer-readable media contained herein refers to a mass storage device, such as a hard disk or CD-ROM drive, it should be appreciated by those skilled in the art that computer-readable storage media can be any available computer storage media that can be accessed by the computer 600.

By way of example, and not limitation, computer-readable storage media may include volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data. For example, computer-readable storage media includes, but is not limited to, RAM, ROM, EPROM, EEPROM, flash memory or other solid state memory technology, CD-ROM, digital versatile disks (“DVD”), HD-DVD, BLU-RAY, or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium which can be used to store the desired information and which can be accessed by the computer 600.

It should be appreciated that the computer-readable media disclosed herein also encompasses communication media. Communication media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer readable media. Computer-readable storage media does not encompass communication media.

According to various embodiments, the computer 600 may operate in a networked environment using logical connections to remote computers through a network such as the network 620. The computer 600 may connect to the network 620 through a network interface unit 606 connected to the bus 604. It should be appreciated that the network interface unit 606 may also be utilized to connect to other types of networks and remote computer systems. The computer 600 may also include an input/output controller 612 for receiving and processing input from a number of other devices, including a keyboard, mouse, or electronic stylus (not shown in FIG. 6 ). Similarly, an input/output controller may provide output to a display screen, a printer, or other type of output device (also not shown in FIG. 6 ).

As mentioned briefly above, a number of program modules and data files may be stored in the mass storage device 610 and RAM 614 of the computer 600, including an operating system 618 suitable for controlling the operation of a networked desktop, laptop, or server computer. The mass storage device 610 and RAM 614 may also store one or more program modules. In particular, the mass storage device 610 and the RAM 614 may store the document editing program 116, the meeting service 118, and/or the other software components described above. The mass storage device 610 and RAM 614 may also store other program modules and data, such as the document 120.

In general, software applications or modules may, when loaded into the CPU 602 and executed, transform the CPU 602 and the overall computer 600 from a general-purpose computing system into a special-purpose computing system customized to perform the functionality presented herein. The CPU 602 may be constructed from any number of transistors or other discrete circuit elements, which may individually or collectively assume any number of states. More specifically, the CPU 602 may operate as one or more finite-state machines, in response to executable instructions contained within the software or modules. These computer-executable instructions may transform the CPU 602 by specifying how the CPU 602 transitions between states, thereby physically transforming the transistors or other discrete hardware elements constituting the CPU 602.

Encoding the software or modules onto a mass storage device may also transform the physical structure of the mass storage device or associated computer readable storage media. The specific transformation of physical structure may depend on various factors, in different implementations of this description. Examples of such factors may include, but are not limited to: the technology used to implement the computer readable storage media, whether the computer readable storage media are characterized as primary or secondary storage, and the like. For example, if the computer readable storage media is implemented as semiconductor-based memory, the software or modules may transform the physical state of the semiconductor memory, when the software is encoded therein. For example, the software may transform the states of transistors, capacitors, or other discrete circuit elements constituting the semiconductor memory.

As another example, the computer readable storage media may be implemented using magnetic or optical technology. In such implementations, the software or modules may transform the physical state of magnetic or optical media, when the software is encoded therein. These transformations may include altering the magnetic characteristics of particular locations within given magnetic media. These transformations may also include altering the physical features or characteristics of particular locations within given optical media, to change the optical characteristics of those locations. Other transformations of physical media are possible without departing from the scope and spirit of the present description, with the foregoing examples provided only to facilitate this discussion.
